Required prior knowledge: - scientifical terminology and conventions about the chemical

phenomena studied;

- the classification of the composites, solutions, elements, molecules

and chemical reactions;

- the structural characteristics of different atoms.

Objectives: At the end of the module the students will be able to

• Define the atom, chemical element and symbol

• State Mendeleev’s periodicity law

• Recognise the structure of the periodical system

• Define the groups and periods

• Classify the elements based on the position in the system

chemical elements.

Resources: colours, water colours, colored paper, colored chalk

Time frame: 5 lessons (50 minutes/lesson)

Arts involved: drawing, drama, poetry

Methods of work: group work,

Procedure / steps:

Lesson 1 – classifying the elements

Through a wordsearch worksheet about the chemical elements the students find out the

name of the chemist who gave us the modern classification of the elements,

Then the students learn about the criteria used to classify the elements.

Lesson 2 – the periodical system

The teacher presents the periodical system by Mendeleev and through a game they

discover by themselves how the chemist arranged the elements in the system. Each student

chooses a different element (out of the first 20) and h

Lessons 4&5 – the story of the periodical system

Having acquired all the information about the periodical system the students are faced

with a challenge. They have to work together and create their own story of the periodical

system. The teacher gives the students the setting, the town where the elements reside, and

each student has to take the role of a different element. The students have to create a

description of their element in verse but also to draw it and to make an “ID” card for it. Aft

students finish creating their verses and drawings they film everything like a short drama entitled

He’s at the base of matter

In a world being a host

All the people consider it indivisible

And Democrit named it ATOM

Two atoms considered

That they are true brothers

Always walk together

And they form our MOLECULE

Lots of scientists searched them

And they named them

Not to be tangled

And with symbols they were called

So anybody could know them

Even you seventh year students

CHEMICAL ELEMENTS

We do not know anything about the atom,

Just ... how much is learned by man.

The atom is the infinite little,

Little is small but endless,

Everybody's got a little piece,

And together they all have nothing.

It's the question that hurts us,

If the atom is a flower,

What brings a greater evil,

Or horror ... destructive?

He is the little gentle,

That is not seen in motion,

But he has so much to say,

That never will it be broken.

The smallest of all atoms, but my older brothers

I’m in the bomb that destroys, and in the light of the hard ones

I find myself everywhere: in the air, and in the field used as a fertilizer.

And in liquid state I'm real freezer, odorless and colorless.

Being in plants, animals base their lives on the earth, making proteins.

If you want to have everything, live well with the nitrogen!

I am a perfect actor

When I want I am a diamond

Fullerene or graphite

Or heating coal.

And if you’re intoxicated

Drink activated charcoal.

I am diverse, liked by all.

Silver is my name

Bright and expensive always I am

I'm the most beautiful and the most valuable

Solid, powerful and great.

In teeth it is found

From milk it does come

I'm friend with Uranium.

I am a metal But not a regular one,

But unlike the others I can make ,,boom"

I am famous ROBY

Because I am dangerous

But I am explosive

Only when I am used abusively

No I am not plutonium

I am uranium.

All the students were actively involved in the module, each of them having a specific task

They really enjoyed the role play, and although it all seemed like a game, they took the assignment very

seriously and thus, at the end, they realized that they had acquired new knowledge without a lot of effort

but only by playing and using their imagination and creativity.
